Assume there was a law where GPTs cannot train on data from websites that put up a "Do not crawl" notice. If everyone did this, doesn't the value of the GPT diminish?
It does diminish and hence the question, what is the value the website owner is getting by having their data be used by someone else. (others have called out the same concern).
In your case, you seem to be fine with your data getting used for free. Others are not, especially if the art, data etc. on their website is something they want to earn their livelihood from.
Btw if you can't get MidJourney to create anything that looks like this artist's work, it does not mean it's impossible. Perhaps something with your prompt or perhaps it's something MidJourney will fix eventually. Once it does, the artist has simply lost opportunity to get some value from their own work.
